The results indicate the possibility of multiple recycling of polyurethane foam waste. Glycolates derived from multiple recycling of PU biofoams can potentially be used as additives to polyurethane compositions. This approach allows for PU waste management and is consistent with the idea of a circular economy.In the next stage of research, 4th and 5th degree rebiopolyols will be obtained. Subsequently, one of the biopolyols will be selected for PU foam synthesis. The formulations and recycling
